The tech event returned to an in-person format this year, subject to some constraints and limited to 40,000 participants, after the COVID-19 Coronavirus pandemic forced it to go virtual in 2020. It welcomes more than two thousand start-ups, a thousand investors, and more than 700 speakers.//ZEDJAMESON_SIPA.146/2111041656
